Title:
HEAT EXCHANGER
Document Type and Number:
Japanese Patent JP3826791
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a heat exchanger capable of reducing costs and improving reliability of air tightness by simplifying a connection structure between a fluid passage hole 100a in a porous flat tube 100 and header tanks 210, 220.
SOLUTION: Slits 110a, 120a of a designated depth are cut over a width direction of a flat surface of the porous flat tube 100. The fluid passage hole 100a and the header tanks 110a, 120a are connected with the slits 110a, 120a. Accordingly, the connecting structure between the fluid passage hole 100a in the porous flat tube 100 and each header tank 211, 221 is simplified to reduce cost and improve reliability of air tightness.
